The renovation of the master bathroom in my 83-year-old father’s new house turned out beautifully, with a frameless glass shower and handmade ceramic tile accents. Neither of us wanted to make it look institutional with a grab bar.

Take, for instance, the corner shelf from American Standard’s Invisia line. It looks like nothing more than a solid white tray set inside a tubular frame. But that tube, available in brushed stainless or chrome, functions as a grab bar and can support up to 500 pounds.

Want fun and funky? Best Bath Systems has a series of acrylic towel bars with hidden mounts that come in more than two dozen colors — some opaque, some translucent, some with embedded stones and some that even glow in the dark.

Or, for a spa feel, the company makes a teak grab bar that comes in six lengths, from 10 inches to 42 inches. Mounting hardware is available in five finishes.

“We realized there were a lot of people who wanted an attractive option for safety, and who didn’t want to be reminded of their inabilities first thing in the morning and last thing at night,” said Abbie Sladick, 53, of Naples, Fla., a certified contractor and remodeler who created the Great Grabz line. The line was purchased by Best Bath Systems last year for an undisclosed amount.

Still, I wondered what having a grab bar in the bathroom might do to the eventual resale value of the house. Turns out that it might help it.

A 2012 survey found that about half of respondents ages 55 to 64 thought that bathroom aids such as grab bars and shower seating were “essential” or “desirable.” The proportion rose to almost two-thirds among those age 65 and older. Even in the younger age groups, about a third of those surveyed agreed.

The National Association of Home Builders’ online survey of more than 3,860 respondents included only those who had purchased a house during the past three years or were planning to do so in the next three years — in other words, people who were “really thinking” about what they wanted in a home, said Stephen Melman, the association’s director of economic services.

Although people 85 and older are the most likely to slip and fall, no age group is immune, statistics show. Almost 22 million people older than 15 went to the hospital because of a bathroom injury in 2008, according to the Centers for Disease Control and Prevention. Falls accounted for more than 80 percent of the injuries.

Although 85 percent of those taken to a hospital were treated and released, the injuries still resulted in about $67.3 billion in lifetime medical costs, the CDC said.

Some things to think about when choosing a grab bar:

• Consider the weight of the people who will be using it.

Some bars are rated to support up to 250 pounds, the amount required to comply with the Americans With Disabilities Act; others support up to 500 pounds.

• Compare prices and quality. The Invisia shampoo shelf retails for about $285 online, depending on the finish, while one made by Moen is available at Home Depot for about $40.

• Be aware of how it will be mounted. If you haven’t reinforced the back of your shower or tub with plywood, you’ll probably need a bar with 16-inch offsets or multiples thereof to secure it properly.

• Many people think of grab bars for the shower and bathtub but consider putting one near the toilet, too. The 10-inch bars from Best Bath Systems can be mounted to hold a roll of toilet paper. Invisia makes a more substantial, 13-inch-tall arched toilet paper holder.
